Title: Improvements in telephone systems
IPC: H04Q3/00
Filed: 1924-05-16
Abstract: 219,942. Western Etectric Co., Ltd., (Assigeees of Butz, E. D.). July 31, 1923, [Convention date]. Automatic exchange systems.- In the case of a subscriber entitled only to restricted service calling an operator, a common tone circuit becomes connected to the test wire at the line switch and gives a distinctive signal to the operator. In the system described, a call is extended to an operator's position RT over primary and secondary line switches LS, L<1>S<1> of the plunger type, a repeater R, a trunk 203, 204 and a selector S of the Strowger type. The calling line is extended bv the line switches in the usual manner to the repeater R, and line relay 110 energizes and connects up sluggish relay 111 which feeds back ground on the test wire 112. The line relay 200 of the selector S energizes in series with coil 113 and connects up sluggish relay 206. The subscriber dials the digit assigned to the operator, and at the first de-energization of relay 110, slow-release relay 122 operates, so that the impulses are repeated at contact 119 to relay 200, and thence to the vertical magnet 207. Series relay 208 falls back after the last impulse in the usual way and releases magnet 209 which advances the side switch to the 2nd position, in which the rotary magnet 211 operates. Magnet 209 is connected up and remains energized as long as the test wiper engages grounded terminals, but releases when an idle line is found and advances the side switch to the 3rd position, thus stopping the rotation. Relay 202 now energizes and switches through the speaking conductors, whereupon the line relay 216 at the operator's position energizes and closes a circuit through the key K for relay 217, which lights a lamp 219, and relay 218, which feeds back holding ground to the selector S. The tone transformer 132 is connected over springs 125, 126 controlled by the plunger magnet B of the primary line switch and the test wire 112 to the upper winding of coil 113, the lower winding of which is bridged across the speaking conductors; consequently the operator hears a distinctive signal upon throwing the key K to the left. When the key K is thrown to the right, relay 217 is disconnected, but the head set remains in circuit. The subscriber gives his order to the operator and hangs up, and is recalled when the desired connection is available. If three-wire trunks are employed, the test wire 112 is connected directly to contact 220 in the selector S, and the tone signal is transmitted through the windings of relay 218.
